Plasterer&#39;s ground



B. E. Bl GGlN PLASTERER S- GROUND 7 Oct. 7, 1930.

.Filed Sept. 14. 1927 gmmtoz 'Bm'r' E BIGGIN bars 7 as the guide, so that when the plaster is flush with the outer walls of said legs the desired depth of application will have been reached without further attention on the part of the plasterer. The construction enables the work to be carried on rapidly and with accuracy, to the end of producing a square, smooth finished and uniformly applied plaster base with minimum difficulty. struction has the advantage of being of exceptionally strong construction, capable of being applied and removed with convenience with regard to the associated frame work, and it is of such staunch construction that injury to the ground when the same is being placed in position is extremely unlikely. Moreover, by the provision or theturn-buckle arrangement a very fine adjustment on the part of the bars may .be eiiected for spacing purposes, and it will be observed that this adjustment is independent of the means provided for securing the anchor plate to the frame work. In the form of the invention disclosed in Figure 5 the bars 7 are provided with screws 8 having individual adjusting nuts 16 which are carried by the anchor plates 11. By this arrangement independent adjustment may be given to each bar so that the plaster base on the adjacent wall surfaces may be varied and. also to overcome irregularities which may exist in the positioning of the anchor plates.

What is claimed-is:

1. A plasterers ground comprising a pair of parallel angle bars, anchor plates arranged between said bars and rovided with outwardly directed bearing anges having openings therein, right and left handed screws connected with said bars and having the threaded ends thereof loosely received within said openings respectively, and a turn buckle disposed between said bearing flanges of'eaeh anchor plate and having threaded engagement with the inner ends of adjacent screws.

2. A plasterers ground comprising a pair of parallel bars, anchor plates arranged between said bars and adapted to be mounted to the frame of a wall opening, each oi said plates being provided with outwardly directed flanges having openings formed therein, threaded screws connected with said bars and having the threaded ends thereof received within said openings respectively, and threaded means cooperating with the screws and flanges for controlling the relative spacing of said bars. I i

3'. A plasterers ground comprising a pair of vertically disposed parallelly arranged bars, spaced anchoring members positioned between said bars and adapted to be applied to the frame structure of a wall opening, each of said members being formedwith two pairs of horizontally arranged bearings, threaded screws connected with saidbars and The con I through said bearings, and turn buckles eugaging the threaded ends of said screws and mounted for rotation within said bearings.

In testimony whereof I aflix my signature.
